I’ve had a couple TGW71 PCBs for an absolute age (original board by @the_pokemon_kid)
It was my first SMD soldering project, I love the layout of a 60% plus arrows and nav cluster, and the RGB indicator light between them.
I’ve been planning an inexpensive case for them for a while but never got around to it.
I’m a fan of vintage mechanical keyboards (take a look at my post history!) and have a lot of beige, but thought that wouldn’t transfer over well to an acrylic sandwich case
Instead I thought I’d use the Sinclair ZX Spectrum family family for inspiration (particularly the the ones that came after the 48k),
I thought it was a good fit seeing as they have the same design philosophy in terms of keeping the costs low, and they use blocky aesthetics that could be emulated with an acrylic sandwich case.
My design uses vertical pieces of acrylic to slot into the case to have designs visible on multiple faces, and also to add some rigidity by keying into place.
I’m planning for the black layers of the case to be matte, though I haven’t settled on a material yet (not sure on the pros/cons of high impact polystyrene, ABS etc.) if anyone has any thoughts please let me know!
I rendered it with WoB keycaps because I have a spare set (so that’s probably what will end up on them) and it matches the WoB scheme used on all ZX Spectrums except the 48k. It would look great with KAM wraith keycaps too.
I originally planned on the plate being aluminium, but it came out as too expensive so I’m looking at PETG instead.
Since the first renders I made some changes to the plate design, and the pen rest (seeing as the design does not use 3mm black acrylic anywhere) I changed it so it can be either a solid piece (as before) or multiple to mirror the stripes of the top right of the board. This is how it’s looking at the moment:
This is also the first big(ish) thing I’ve designed in CAD (Fusion 360), so I’m looking for feedback, especially on how I can improve the rendering.
I’m currently looking at getting it made and waiting for some quotes to come back. Having quickly looked at ebay, the materials alone cost about £30.
